To all whom it may concern:

Be it known that I, HAROLD D. CHURCH, a citizen of the United States, and'resident of Detroit, WVayne County, State of Michigan, have invented certain new and useful Improvements in Hydrocarbon Motors, of which the following is a specification.

This invention relates to hydrocarbon motors and more particularly to temperature regulating means for oil pumps employed in connection with said motors.

One object of the invention is to provide means for maintaining an equable temperature of the body of the oil pump, to thereby facilitate the flow of oil in cold weather upon starting and prevent undue evaporation, frothiness and possible carbonization of the oil due to excessive heat.

Another object of the invention is to enable the utilization of the thermostatically controlled by-pass now employed in connection with the radiator and water pump, in accomplishing these ends.

With the above objects and. others in view. the invention is embodied in preferable form in the construction and arrangement hereinafter described and illustrated.

in the accompanying drawings, in which:

Fig. 1 is a .side view in elevation, partly in vertical section,

Fig. 2 is an end view in elevation of a hydrocarbon motor showing one form of the invention applied thereto, and

Fig. 3 is a View similar to Fig. 2 showing another form of the invention, and'the section at the upper part is substantially on the line 3-3 of Fig. 1.

Referring to the drawings and first to the device of Figs. 1 and 2, 10 indicates a hydrocarbon motor of any desired type, and 11 a water jacket surrounding the cylinders thereof.

Leading from the upper part of the water jacket of the motor is a pipe 12 which communicates with a chamber 13in which is adapted to be mounted a thermostat and valves controlled thereby. From the chamber 13 a pipe 14 leads to the upper part of a radiator 15. From the lower part of the radiator a pipe 16 leads to the suction end of a water pump 17. The delivery end of this water pump communicates with a pipe 18 leading to the'lower part of the water jacket 11 of the moto and the section end of the pump eommmneetes with a bypass pipe 19 leading back to the chamber 13 in which is mounted the thermostat and valve. Interposeol in theline of the pipe 18 is a water jacket 20 surrounding an oil pump'21. This water jacket of the oil pump is adapted to have communication with the water circulation system for the purpose of warming the oil pump upon starting the engine and also for the purpose of cooling the pump when the temperature reaches an undesirable height, the thermostat operating to cut off direct communication from the motor water jacket to the water jacket of the oil pump when the temperature of the water in the system rises to-a predetermined degree. It will be seen that this may be done by utilizing the thermostatic control, and bypass now sometimes employed in motor vehicles for maintaining the circulation of the water around the engine only upon starting, so as to assist in warming the motor during the initial operation thereof and which arrangement provides for the automatic establishment of communication with the radiator when the temperature of the water in the engine water jacket rises to a certain point. It is clear, however, that the present invention may be carried out by an arrangement of bypass pipe, thermostat and" valves which is independent of the'radiator cut-out means heretofore employed.

Referring to the control device, a valve 22 connected to the stem of a thermostat 23 is held by the contracted condition of the thermostat against a seat 24 at the junction between the pipe .12 and pipe 14. the latter leading to the radiator, so that communication between the motor water jacket and the radiator is cut off. At the same time. a valve 25 also carried by the stem of the thermostat is held away from a seat 26 at the junction 26. of the chamber 13 with the by-pass pipe 19 so that the water is free entirely close and cut off the flow of water.

thru the by-pass 19 and at that time all of the water will flow thru the radiator 15 -where it will be considerably cooled before it reaches the water pump 17 by which it is forced thru the pipe 18 to the motor jacket. This relatively cool water. passing thru the jacket of the oil pump 21 will prevent the oil in the motor crank case from becoming too hot and will in fact keep it at a substantially even temperature.

In Fig. 3 a form of the invention is illustrated in which the thermostat and valves operate only to warm the water jacket of the oil pump upon starting. without reducing the temperature of the water jacket by establishing communication with the radiator as in the arrangement illustrated in Figs. 1 and 2. In the form shown in Fig. 3, 26 is the motor, 27 the motor water jacket and 28 a pipe leading from the upper end of the motor water jacket to a chamber 29. In this chamber is located a thermostat 30 adapted to operate a valve 31 and a valve 32, like valves 22 and 25. The latter valve ontrols the passageway of a pipe 33 leading through the water jacket 34 of an oil pump 35 from the opposite end of which water jacket a pipe 36 leads to the suction end of a water pump 37 The delivery pipe 38 of said pump communicates by a pipe 39 with the lower part of the water jacket of the motor.

In the arrangement thus described, when the engine is first started, the communication from the water jacket of the motor to the by-pass and thence to the water jacket of the oil pump will be open. and as the'engi ne warms'up the water will be warm and Wlll in turn impart its heat to the oil pump, thus facilitating the flow of oil. When the heat of the water becomes excessive the thermostat will be expanded thus closing the valve 32 controlling the by-pass and cutting off the flow of water through the water acket of the oil pump. The oil pump water acket is thereafter closed from communication with the motor circulation system until the engine ceases to operate and cools ofi.

Having thus described my invention,what I claim and desire to secure by Letters Patent is Y a 1. In 'a hydrocarbon motor, the combination with the water jacket thereof, the water circulation pump, and the radiator, of a jacketed oil pump for the motor, and thermostatically controlled means for directing the water to the radiator or to the jacket of the oil pump without passing thru the radiator.

2. In a hydrocarbon motor, the combination with the water jacket thereof, the water circulation pump, and the radiator, of a jacketed oil pump for the motor, a by-pass, and valve and thermostat means which in one position cuts off the radiator and directs the water thru the by-pass to the jacket of the oil ,pump and in another position cuts off the by-pass and directs the water to the radiator.

3. In a hydrocarbon motor, the combination with the water jacket thereof, the water circulation pump, the radiator, and a bypass around the radiator, of a jacketed oil pump for the motor arranged in the circulation system so that its jacket receives water from the motor jacket direct when the by-pass is in operation, and a thermostatic device for cutting off the radiator from communicating with the motor jacket outlet and directing the water thru the by-pass.

4. In a hydrocarbon motor, the combination with the water jacket thereof, the water circulation pump, the radiator, and a byass around the radiator, of an oil pump' having a water jacket arranged between the outlet side of the water pump and the motor jacket, and a thermostatic valve controlling the flow of water thru said by-pass.

5. In a hydrocarbon motor, the combination'with the water jacket thereof. the radiator, anda bypass around the radiator, of a water jacketed oil pump having its jacket in the piping from the radiator outlet to the motor jacket inlet, and a. thermostatic valve controlling the flow of water to the by-pass.

. 6. In a hydrocarbon motor, the combination with the water jacket thereof, the radia tor, and'a by-pass around the radiator. of a water jacketed oil pump having its jacket in the piping from the radiator outlet to the motor jacket inlet, and between said bypass and the motor jacket inlet, and a valve controlling the flow of water to the by-pass.

In testimony whereof I aflix my signature.
